Ground-state properties of exotic Si, S, Ar and Ca isotopes

Abstract Masses, deformations, radii, two-neutron separation energies and single-particle properties of Si, S, Ar and Ca isotopes are investigated in the framework of the self-consistent mean-field theory. In particular, the role of the N = 28 gap in the neutron-rich isotopes, and differences between proton and neutron deformations are discussed.
